They are not barred from going to university but if they start proselytizing they are usually removed. That is the law in Iran and they know it yet they insist on breaking it. If they can't keep their mouths shut, it's there problem.

Let me tell you something: Baha'i claim there are about 300,000 Baha'is in Iran. Give each a lifespan of 60 years and you will have about 300,000/60 = 50,000 Baha'is in Iran reaching university age every year. The vast majority of these enter university and finish their studies without a problem. A very very small minority are removed due to proselytizing. These few are immediately used by the Baha'i UHJ as pawns for their game of playing the victim and propaganda against Iran.

The religious always complain when people from another religion do missionary work in their area, but they themselves go batshit when their own missionary work in other people's areas is discouraged or prohibited. "Yeah, but mine is the real truth!" Yeah, sure.

That's not how division works and people are not going to be uniformly distributed by age.
